WAGSS discusses the key operations and advantages of Colloidal Mixers

While traditional paddle type mixing have achieved considerable success in the past, there are some noteworthy advantages to using colloidal mixers.

The colloidal pump itself is the decisive component of WAGSS colloidal mixers. The rotor within the pump runs at speed of 2000rpm and is located only 3mm from the walls of the inner housing where the turbulence and shearing action all happens.

Acting as a centrifugal separator, the WAGSS colloidal mixer circulates heavier grout towards the outside of the tank to mix with the lighter grout and then pushed through the centre vortex towards the colloidal pump. Once through the mixer the process is then repeated over until multiple passes are made and until the entire mix becomes uniform and the centrifugal action can no longer separate differing densities. Using the WAGSS 25II colloidal mixer, this process is finalised in under 30 seconds using a 350 ltr mixing tank.

The fundamental concept behind the colloidal mixer ensures that every chemically activated particle is hydrated for maximum strength and durability - The aggressive break down of all cement grains and separation from each other until they are all independently surrounded by a film of water. Such a process contributes to an astounding cost saving

The WAGSS colloidal mixers handle cement/water ratios down to approx 0.34. Such figures make them perfectly suited to cable bolting where the optimal water cement ratio should be between 0.35 ( 7 ltrs water per 20 kg cement) to 0.4 ( 8 ltrs water per 20 kg cement).
